Before you start developing applications on MapR’s Converged Data Platform, consider how you will get the data onto the platform, the format it will be stored in, the type of processing or modeling that is required, and how the data will be accessed.

A MapR Ecosystem Pack (MEP) provides a set of ecosystem components that work together on one or more MapR cluster versions. Only one version of each ecosystem component is available in each MEP. For example, only one version of Hive and one version of Spark is supported in a MEP.

MapR supports public APIs for MapR-FS, MapR-DB, and MapR-ES. These APIs are available for application development purposes.

Configure Hue to use MapR-SASL

You can configure Hue to use MapR-SASL for its communications with various components on
a secure MapR cluster. Hue automatically detects and sets the security configuration of
the cluster and its components. Therefore, in some cases, minimal configuration is
required.

This topic includes instructions to complete the MapR-SASL configuration for:

Hive

Sqoop2

HttpFS

Oozie

YARN

Note: After you configure the hue.ini, you must restart Hue. However, if
you configure multiple sections of the same file, you can restart Hue one time after
your updates are complete.

Configure Hue to use MapR-SASL for Hive

Hue can use MapR-SASL to communicate with Hive on a secure MapR cluster.

When Hive is configured to use MapR-SASL and the cluster is
secure, Hue automatically uses MapR-SASL with Hive.

Configure Hue to use MapR-SASL for Sqoop2

Hue can use MapR-SASL to communicate with Sqoop2 on a secure MapR cluster.

When Sqoop2 is configured to use MapR-SASL and the cluster is
secure, Hue automatically uses MapR-SASL with Sqoop2.

Configure Hue to use MapR-SASL for HttpFS

Hue uses MapR-SASL to communicate with HttpFS 1.0 on a secure MapR cluster.

The default hui.ini file that is installed with Hue includes the following
configurations that allow Hue to automatically detect and set the security
configuration:
